  The paper presents the suppressive effect of different concentration of aqueous leaf extracts of Neem (Azadirachta indica) on some agricultural crops e.g. Cicer arietinum L., Brassica juncea (L.) Czern and Coss; Cucumis sativus L.; Phaseolus mungo L.; Raphanus sativus L.; and Vigna unguiculata (L.) Walp. The experiment was conducted in sterilized petridishes with a photoperiod of 24 hours on an average temperature of 29.50C. The result showed that aqueous leaf extract of Azadirachta indica caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor plants. The effect was proportional to the concentrations of the extracts and higher concentration had the stronger inhibitory effect whereas in some cases the lower concentration showed stimulatory effect. The study also revealed that inhibitory effect was much pronounced in root and lateral root development rather than shoot and germination.

  The anatomical studies of the kidneys of Rhode Island Red (RIR) and White Leghorn (WLH) chicken during their postnatal stages of growth and development were investigated in the present study. The chicken were grouped into day old, day 30, day 90, day 180 and day 360.The gross structures of the kidney (weight, relative weight, length, breadth and thickness) during their growth period were estimated by using the measuring balance and scale. The histological structures of the kidney (the nephrons, the number of glumerulae and the presence of collagen and elastic fibers within the kidney) were also studied by light microscope using hematoxylin and eosin stain, Van Gieson and Verhoeff`s stain. The gross structures were significantly higher in the RIR than the WLH chicken whereas the histological structure (number of glomerulae) were higher in WLH than RIR chicken. From these data it may be suggested that these differences did not depend on the developmental stages of growth and development but depend on the genetic variation of the chicken.

  Allelopathic effect of leaf extracts (different concentration) of Acacia auriculiformis and its possible phytotoxicity was tested in a laboratory experiment by using some agricultural crops e.g. Brassica juncea (L.) Czern & Coss; Phaseolus mungo L.; Raphanus sativus L. and Vigna unguiculata (L.) Walp. and Cicer arietinum L. as a bioassay material. The experiment was conducted in sterilized petri dishes with a photoperiod of 24 hours on an average of 29°C. The effects of the different concentrations of aqueous extracts were compared to distill water (control.). The aqueous extracts caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor plants. Bioassays indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration (50-100%) had the stronger inhibitory effect whereas in some cases the lower concentration (10-25%) showed stimulatory effect. The study also revealed that inhibitory effect was much pronounced in root and lateral root development rather than germination and shoot growth.

  The study describes the effect of 2 (two) commonly used inorganic fertilizers (Urea and TSP) on Anthocephalus chinensis (Lam.) Rich ex. walp. seedlings in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong, Bangladesh with a view to standardize an optimum dose of inorganic fertilizers for raising quality seedlings. There were combinations of 16 treatments including a control one (NoPo). Seedlings were supplied 0, 75,175, 300 kg ha 1 of N and P of each in solution form in all possible combinations. Seedlings were evaluated for 13 weeks (90 days) in the nursery. Seedling mortality along with different growth parameters was measured. Different growth variables were also calculated. Seedling growth was in general markedly better for fertilized one in comparison to the control one. Nitrogen addition was found significantly promoting the collar dia. increment and total dry matter production of seedlings. Seedling mortality was observed as the nitrogen dose increases. Significant variation was not observed for different growth variables due to nitrogen doses. However, there was no significant variation in any parameters for different levels of phosphorus applied. The study suggests that application of 175 kg N ha 1 may be beneficial and also addition of 175 kg P ha 1 may boost the diameter, total dry matter production and leaf area of Anthocephalus chinensis on this type of soil (forest top soil collected from Chittagong University Campus).

  Allelopathic effects of different concentration of water extracts of Eupatorium odoratum leaf on germination and growth behavior were tested by using some agricultural crops e.g. Cicer arietinum; Brassica juncea; Cucumis sativus; Phaseolus mungo; Raphanus sativus and Vigna unguiculata as bioassay material. The experiment was conducted in sterilized petridishes with a photoperiod of 24 h on average temperature of 28.50C. The effect of the different concentration of aqueous extracts was compared to distil water (control). The result revealed that different concentrations of Eupatorium odoratum leaf extracts caused significant inhibitory effect on germination, root and shoot elongation and development of lateral roots of receptor crops. Bioassays indicated that the inhibitory effect was proportional to the concentrations of the extracts and higher concentration had the stronger inhibitory effect whereas in some cases the lower concentration showed stimulatory effect. The study also revealed that inhibitory effect was much pronounced in root and lateral root development rather than shoot and germination.

  Feeds and fodder and the quantities fed to large ruminants (cattle and buffalo) in eight different areas of Bangladesh involving 96 farmers were recorded for a year from January 1988 to 1989. Roughage like straw naturally available seasonal green grass and weds, tree leaves, water hyacinth, legumes and sugarcane tops were the major feeds offered to the animal by a bigger proportion of farmers in the study areas. It was found that amount varied (P<0.01) from area to area. The overall consumption of straw, green grass, leaves, legumes and sugarcane tops per day and head were 1.9+2.6, 5.1+4.9, 0.3+2.0, 0.1+1.0 and 0.01+0.07 kg respectively. By product concentrates, mostly rice bran, wheat bran and different oil cakes were offered to the animals in the studied areas. However, the amounts offered also varied (P<0.01) from area to area. Consumption of as fed rice bran, wheat bran and oil cakes were 0.5+0.7, 0.03+0.1 and 0.01+0.03 kg, respectively. The means and standard deviation indicate a wide range of variations in the amounts of roughage and concentrates offered. Furthermore assignment was the not systematic due to the availability of foodstuffs, lack of knowledge of farmers and consequences of the inefficient utilization of available feed resources. In addition to feeding roughage and concentrates, farmers graded their animals 6.2 h on an average a day. Grazing also varied (P<0.01) with different areas. It is thus concluded that feeds and feeding and the assignment amount of roughage and concentrates to the large ruminants are very poor practices of large ruminants exercised in Bangladesh. The assignment amounts are however, not upto the requirement of animals. Feeding animals should be improved by exploring the unconventional feeds of those areas and also by the best management and utilization of available resources. Farmer·s knowledge about feeding practices of animals should also be improved to increase animal production in Bangladesh through proper research extension linkages.

  An experiment was conducted to find out the importance of various characteristics of mammary system and to study their relationship with milk yield in dairy cows during the period from October to November 2000. By a previously prepared module, 100 dairy cows were selected to collection of data for the various measurements and shapes of udder from the Bangladesh Agricultural University Dairy Farm and adjacent villages of University. The phenotypic correlation coefficients between udder measurements and test milk yield and between all possible combinations of udder measurements were significant (P<0.01), revealed that length, width and depth of udder were related to each other and also to the milk production. A bowl shaped udder with large proportion of secretory tissue with highest milk production was as an assets for a milch cow. It may be concluded that a well conformation of udder is to be considered for selecting dairy cows on milk yield.

  The study describes the effect of 2 commonly used inorganic fertilizers (Urea and TSP) on Michelia champaca Linn. seedlings in the nursery of the Institute of Forestry and Environmental Sciences, University of Chittagong, Bangladesh with a view to standardize an optimum doze of inorganic fertilizers for raising quality seedlings. There were combinations of 16 treatments including a control one (NoPo). Seedlings were supplied 0, 50, 77 and 175 kg ha-1 of N and P of each in solution form in all possible combinations. Seedlings were evaluated for 22 weeks (150 days) in the nursery. Seedling mortality along with different growth parameters was measured. Different growth variables were also calculated. The fertilization that seedling growth was in general markedly better for fertilized one in comparison to the control one. Nitrogen additions significantly promoting the collar dia. increment and total dry matter production of seedlings experimented. Seedling mortality was not noticed. The  study suggested that application of nitrogen and phosphorus (77 kg N ha-1+ 77 kg P ha-1) on this type of soil (forest top soil collected from Chittagong University Campus) is necessary to boost the diameter and total dry matter production of M. champaca seedlings.

  The effect of various tranquilizer and sedative agents was studied in sheep. The respiration rates, pulse rates and rectal temperature in sheep reduced significantly (P<0.01) with all the tranquilizing and sedative agents except promethazine hydrochloride. The chlorpromazine hydrochloride produced longest onset and shortest duration of sedation and recovery period, while xylazine hydrochloride produced shortest onset and longest duration of sedation and recovery period. Xylazine hydrochloride and diazepam decreased the rumen motility significantly (P<0.01) whereas chlorpromazine hydrochloride and promethazine hydrochloride decreased insignificantly. Hemoglobin (Hb) and packed cell volume decreased significantly (P<0.01) compared with the pre-sedative control values with all the above tranquilizers and sedatives except promethazine hydrochloride. Xylazine hydrochloride reduced the PCV in a marginally significant (P<0.05) level. Promethazine hydrochloride significantly (P<0.01) increased the Hb but PCV insignificantly. Xylazine hydrochloride and diazepam produced good sedation in sheep but chlorpromazine hydrochloride produced moderate sedation whereas promethazine hydrochloride only tranquilizes the sheep.

  Naturally infected leaf samples of betelnut having characteristic symptoms of spots were collected from the campus of Khulna University, Bangladesh. The pathogen of this disease was identified on the basis of growth characters, acervuli production and conidial features on PDA medium as Pestalotia palmarum. The species was found pathogenic on excised leaves of the betelnut. Among the six fungicides tested in vitro Bavistin of three doses (100, 200 and 300 ppm) and Tilt 250 EC (100 and 200 ppm) were most effective in inhibiting radial growth of Pestalotia palmarum. Among the seven indigenous plant extracts tested in vitro, two doses (4 and 5%) of garlic (Allium sativum) extracts were found most effective in inhibiting the radial growth of the fungus.

  The experiment was conducted in Itna Upazila, Kishoreganj from July 2001 to June 2002. It has included survey of waterbodies, implementation of different management policies and affect of aquatic environmental issues on hoar fisheries in Itna Upazila, Kishoreganj. There are 16 hoars in Itna Upzila which were comprising of 83 jalmohals. Three management policies including revenue- based leasing system in 93% area of jalmohal, NFMP in 7% area of jalmohal with fisheries resources development project including sanctuary, have been practiced in Itna. Aquatic environmental degradation by siltation, submersible roads and flood control embankments, deforestation, conversion of water body into agricultural land, use of agro-chemicals and surface water abstraction for boro crop, social and political unwanted influence were creating a great threat to fisheries sustainability. It has been suggested that government should emphasize the sustainable haor fisheries development by implementing community-based management practices as part of an integrated holistic development plan of the haor areas.
